We were on the PG in May 2005. We also got a small cake and a couple glasses of Champagne in our cabin on the evening of our anniversary with a congrats letter from the Captain. There were probably 20-25 couples on the ship celebrating an anniversary or a honeymoon. Just make sure their travel agent puts a note in their booking that they are on their honeymoon. Or have them mention it to them when they check in so they get invited to the party.
